VB Electronics
Conference in Bloemfontein

Founded in 1987, VB Electronics was serving the Free State as Electronic Contractors in the fields of two way radio communication, security and sound installations. VB Electronics also install in auditoria, halls and sport stadia. Each installation is preceded by an acoustic analysis to be able to tweak the planned sound system for vocal clarity and intelligibility, regardless of the room acoustics. Having built up a support base of a magnitude of suppliers and brand names, VB Electronics and Acoustics3d can satisfy almost any reasonable budget. This branch is called Acoustics3d. In 2003 a branch was founded in Johannesburg, serving Gauteng and North West. Today they are serving the Free State, Northern Cape and northern parts of the East Cape. Gradually they specialised in Church Sound Installations, a niche market which requires specialised skills due to the unique acoustic challenges of each building.

VB Electronics has 30 years experience in sound reinforcement, public address, line/radio communication and audio/video conference systems. Founded in 1987, VB Electronics was serving the Free State as an electronic contractor in the fields of two way radio communication, security and sound installations. Gradually they specialised in Church Sound Installations, a niche market which requires specialised skills due to the unique acoustic challenges of each building. The public address or sound reinforcement system fitted in a House of Worship is the single most important support system to deliver the Message. Each of the above functions require very specific acoustical and sound reproduction capabilities which is the equivalent of having a room capable being a cathedral, lecture hall, symphony hall and a recording studio all at the same time. Acoustic analysis quantify the performance of the sound system and the room response based on predefined acoustical criteria determined by the specific usage of the room/venue. Room Reverberation Time (rate of decay of sound) using advanced Time Delay Spectrometry (TDS) analysis methods. Acoustic treatment is required when the room/venue acoustics are not suitable for amplified sound and the acoustic incompatibility is beyond the ability of the signal processing equipment to produce intelligible sound. Most Places of Worship are designed with little or no consideration of the sound reinforcement requirements as most older churches and cathedrals were designed for the natural spoken word and the pipe organ performance, whereas modern designs make use of highly reflective surfaces such as glass, steel, granite and marble which causes additional unwanted reflections. In most cases the room is too reflective/reverberant for amplified sound and the walls and/or ceiling require treatment in order to absorb certain sound frequencies to create a uniform and intelligible sound field. This is achieved by the installation of specialised perforated plasterboards or slotted wooden strips backed by various sound absorbing material designed to reduce specific problematic frequencies. The selection of the most suitable type, position and size of the acoustic treatment is identified and optimised through the use of an acoustic computer simulation system in conjunction with actual on-site acoustical measurements taken to ensure the maximum speech intelligibility for the investment made.rly identify any issues and discuss how improvements could be made based on various costing options contained within defined budgetary limits. Natural sound/acoustics originate as a single source and propagates in an omni-directional manner through the room. Amplified sound originate from multiple sound sources which propagates in directional sound fields focused on specific areas/partitions within the room, uniformity is reached through acoustically matching of the various partitions. Natural sound requires a reflective environment and amplified sound an absorbent environment. As natural sound alone cannot meet the demands of the modern places of Worship, the goal is to seek a uniformity for the natural and amplified sound models which is often diametrically opposed. The initial design is completed based on data acquired during the site survey or acoustic analysis conducted to propose solutions relating to various costing options. Equipment selection is done based purely on the available budget and sound reproduction requirements and is not specific to any brand, drawing from a vast supplier base and a multitude of installations where equipment from entry-level to high-end brands have been successfully implemented. If budgetary constraints does not permit full implementation of the required functionality, a phased approach will be proposed without compromising overall system quality (by limiting functionality and not quality). Once a solution has been agreed upon, a comprehensive design is conducted using 3D acoustic modelling and simula
